2 Claims. 1

The invention relates to air conditioning or ventilating apparatus for supplying air to a room or other enclosure and more particularly to those types of such apparatus that are adapted to take their air supply through a wind-ow opening.

The object of the invention is to provide a device of the character above described in which the intake duct may be installed between the opened window and its sill in the desired lengthwise position thereof and in which the motor driven unit is suspended from said intake duct in the desired position back of. the window sill, thus simplifying the installation of the unit and adapting it for use under conditions where a floor supported type of unit could not be used.

A further object of the invention is to provide valve controlled ventilator openings in the duct and in the unit to suit various conditions of operation of the apparatus.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings:

Fig. 1 is a perspective view of an apparatus embodying the invention;

Fig. 2 is a vertical sectional view taken on the line 22 of Fig. 1;

Fig. 3 is a horizontal sectional view taken on the line 33 of Fig. 2;

Fig. 4 is a detailed vertical sectional view taken on the line 4-4 of Fig. 2;

Fig. 5 is a detailed vertical sectional view taken on the line 5-5 of Fig. 3;

Fig. 6 is a detailed sectional view taken on the line B6 of Fig. 3.

The apparatus comprises an intake duct 8 and a ventilator unit 9, means for mounting said duct between an opened window l and its sill II, and means for adjustably suspending the unit 9 from said duct.

The duct 8 comprises a rectangular metal conduit open at its back end and having an inlet opening l2 at its front end covered by a screen l3, said duct having an opening 14 in its bottom intermediate its ends adapted to be closed by a door or valve l pivotally mounted on a shaft l6 extending through the side walls of said duct and having an exteriorly disposed operating handle ll. Where the duct extends through the window opening, it is provided with a collar l8 of box section apertured to provide a channel section [9 with side flanges 20 at its sides, and an angled top portion 2|. The duct 8 may be secured in any desired location lengthwise of the window opening, and for this purpose blocks 22 of wood are sawed ed to a length which permits them to be fitted in the flanges 20 at one end and to abut at their other ends 23 against the window frame 24 and be secured in this position by nails 25 driven through the tops of said sections [9 and into said blocks. Finishing strips 26 of sheet metal are cut to a length to fit between the duct and the sides of the window frame and are formed to provide an outwardly extending flange 21 extending from their reversely bent top edges 23, which flange has a. downwardly projecting watershed portion 29. The strips 26 are firmly held in assembled position with the blocks 22 by the nails 25 which also pass through their flanges 21 as shown in Fig. 5.

The ventilator or air conditioning unit 9 includes a rectangular or square box 30 of sheet metal whose front has an opening 3| therein to telescopically receive the rearwardly projecting end 32 of the duct 8 and whose opposite sides 33 adjacent the bottom have air outlet openings 34, each of which have an adjustable valve or damper 35 associated therewith, each damper being mounted on an adjusting rod 36 pivoted in the front and back of the box and having an exteriorly disposed operating handle 31. The front side 38 of the box is flanged and removably secured to the main body of the box by screws passing through said flanges and the sides 33 so as to permit ready assembly of the parts within said box.

Within the box and adjacent the opening 3| an angled metal frame 39 is secured adapted to receive a filter element 40 and intermediate the ends of the box a metal spider 4| is secured thereto Whose central ring portion 42 is adapted to receive and support an electric motor 43 whose shaft 44 carries a suction fan 45 of any suitable type.

Between the window I!) and the unit 9 the duct rests on a block 45 mounted on the stool portion of the window sill. The portion of the duct 8 extending rearwardly from the block forms a beam or cantilever support from which the unit 9 is suspended, and this unit being slidable on said duct may be moved lengthwise relative thereto to accommodate difierent sizes of window stools. The box 30 is preferably provided with lengthwise extending angled ledges 41 welded or otherwise secured to the sides 33 thereof upon which the bottom portions of the inwardly projecting portion of the duct 8 may ride during the adjustment of the box relative to said duct. The box is moved lengthwise relative to the duct to bring it adjacent the window stool, and its posi- 3 tion relative to the length of the duct being obtained, the lower side of the duct is cut away to form the opening 48, see Figs. 2 and 3.

With the above arrangement, the apparatus may be installed so as to bring the unit 9 over or adjacent one side of a heating radiator within the room to be supplied with air and so that air taken in from the outside by the fan 45 will flow from one of the openings 34 out over the radiator and the other opening 34 will direct unheated air into the room, so that by adjusting the position of the valves 35 for these openings the desired blending of heated and unheated air may be obtained. The valve controlled openings 34 permit regulation of the volume of air delivered by the apparatus and obviated the use of a variable speed drive motor. Also for recirculating air within the room the opening of the valve 15 will allow the fan 45 to draw the air from the room itself and expel it again through one or both of the openings 34. Where the device acts as a plain ventilating unit, the filter 40 may be omitted.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.

What I claim as my invention is:

1. In an apparatus of the character described, the combination of anintake duct adapted to be mounted between an opened window and its sill and having an open end portion projecting inwardly beyond said sill, means for clamping said duct between the window and said sill, an air circulating unit including a box-like metal walled housing having inlet and discharge openings and a motor driven fan in said housing, that portion of said duct projecting from said sill projecting into said inlet opening and into said housing for a distance at least half the length thereof and forming a beam from which said unit is entirely suspended.

2. In an apparatus of the character described, the combination of an intake duct of less width than the window and adapted to be mounted be-- tween the open Window and its sill and having an open end portion projecting inwardly beyond said sill, a box-like member through which the inlet end portion of said duct projects resting on said sill and providing side pockets, wooden blocks mounted in said side pockets and abutting the sides of the window frame and finishing strips extending from said duct over said pockets and block and having flanges projecting over the upper portions of said pockets, and means passing through said flanges, the upper portion of said pockets, and said blocks to secure these parts in relatively fixed position and position said intake in the desired lengthwise location relative to the window opening, a block adjacent the inner edge of the stool of the sill upon which said duct rests, and a ventilating unit connected with and suspended from that portion of said duct projecting beyond said block and sill.
